刷新IdentityServer4的令牌

我们正在实现IdentityServer4并试图弄清楚为什么我们没有获得刷新令牌 . 使用创建的示例我试图确保至少在本地计算机上获得刷新令牌 . 到目前为止没有运气 .

客户端配置如下：

new Client
        {
            ClientId = "client",
            AllowedGrantTypes = GrantTypes.ClientCredentials,
            ClientSecrets = { new Secret("secret".Sha256()) },
            AllowedScopes = { "api1" },
            AllowOfflineAccess = true,
            AccessTokenLifetime = 60,
            IdentityTokenLifetime = 60
        },

使用客户端的测试程序如下所示：

/* CLIENT AUTHENTICATION WITH A KNOWN SECRET */
    var tokenClient = new TokenClient(disco.TokenEndpoint, "client", "secret");
    var tokenResponse = await tokenClient.RequestClientCredentialsAsync("api1");

    if (tokenResponse.IsError)
    {
        Console.WriteLine("TOKEN ERROR:\r\n" + tokenResponse.Error);
        return;
    }

    Console.WriteLine(tokenResponse.Json);

    using (var client = new HttpClient())
    {
        client.SetBearerToken(tokenResponse.AccessToken);

        var numberOfSeconds = 10;

        while( numberOfSeconds < 600 ) 
        {
            Console.WriteLine($"slept for for {numberOfSeconds}");
            Thread.Sleep(10 * 1000);

            var response = await client.GetAsync("http://localhost:52801/api/identity");
            if (!response.IsSuccessStatusCode)
            {
                Console.WriteLine("API ERROR:\r\n" + response.StatusCode);
                break;
            }
            else
            {
                var content = await response.Content.ReadAsStringAsync();
                Console.WriteLine("API RESPONSE:\r\n" + JArray.Parse(content));
            }

            numberOfSeconds += 10;
        }
    }

打印出来的令牌如下所示：

{
  "access_token": "eyJhbGciOiJSUzI1NiIsImtpZCI6IjRkMTJiNjI2MmNmODA0ODBmOTU1YTJhNmEyMDE1MzJlIiwidHlwIjoiSldUIn0.eyJuYmYiO

  "expires_in": 60,
  "token_type": "Bearer"
}

使用访问令牌过期360秒，并且没有刷新令牌可以获得另一个访问令牌 . 有什么明显的东西我不见了吗？

谢谢！
